Updated spotted wing Drosophila management guidelines in Michigan raspberries and blackberries
Updated document provides guidance on minimizing the impact of the invasive pest spotted wing Drosophila in raspberries and blackberries.
As this week’s spotted wing Drosophila (SWD) report shows, catches of this pest are increasing sharply across southern Michigan farms where Michigan State University Extension is monitoring. This highlights the need for growers of susceptible crops that are ripening or ripe to take precautions to minimize the effect of SWD on this year’s crop. There are monitoring techniques that are recommended as well as various cultural and chemical approaches that can be taken, and these are described in detail in the newly-updated document “Spotted Wing Drosophila Management Recommendations for Michigan Raspberry and Blackberry Growers.” This is posted at MSU’s spotted wing Drosophila website as a PDF file that can be downloaded and printed for easy reference.
